ABSTRACT:
An organic electroluminescent device comprising a light-emitting layer between a pair of electrodes, the light-emitting layer comprising a mixture of a hole-transporting material consisting of a tertiary amine compound, an electron-transporting material and a light-emitting additive material, in which the tertiary amine compound has two or more oxidation potentials determined by a cyclic voltammetry wherein a potential difference between the first oxidation potential and the second oxidation potential in the oxidation potentials is 0.22V or more, and a glass transition temperature of at least 100° C., and the electron-transporting material has a glass transition temperature of at least 100° C.
